To all whom it may concern:

Be it known that l, CARL C. GERLACH, a

, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful lm rovements in Compression 'Refrigerating-Machines; and I do hereby ,machines and consists of a simple and efficient apparatus ofthis nature having vaaccompanying drawings rious details of construction, combinations and arrangements of parts hereinafter fully described, shown in the and then specifically defined in the appended claims.

Theinvention consists further in the provision of an oscillating compression refrigerating machine,

medium other than air, in which a rapid Y circulation of air is causedby theoscillating movement of coil, thereby carrymg off the heat of compression rapidly.

My invention is illustrated in the accompanying drawings, in which: I

Figure 1 is a side elevation of the oscill'ating compressor, and Fig. 2 is an end view, a part being broken away.

. Reference now being had to the details of the drawings by letter, A designate two standardsrising from the base B and which are apertured at their upper ends to receive the horizontally disposed oscillating shaft C whichhas a longitudinal duct D therein adapted to communicate with the expansion coil 15 which n turn communicates with the I condenser coil E through the pipe E, havwhich will be operated without a cooling,

' condenser" and an apertured lug T connected therewith through which power may be applied for the purpose of oscillating the same.

l he parts being assembled in the manner shown, the operation of my invention is as follows :When the casing is oscillated, the lever will remain stationary and also the pistons, while the cylinder moves back and forth and creates a suction power similar to that which would be produced if the piston were moved and the gases to be compressed and expanded are drawn through the pipe and forced into the condensing coil and thence pass to the expansion coil, the return of the latter being through the pipe D, thus making a complete cycle.

By the provision of an apparatus embodying the features of my invention, it will be understood that the-means for removing the heat from the apparatus is produced by the rapid circulation of air which is caused by the oscillating movement of the coil and which will tend to carry off the heat of compression.

lit will be noted that, in the operation of the apparatus, boththe expansion and condenser coils oscillate with the casing while the pistons remain stationary.

What ll claim to be new is 2- 1. A refrigerating machine comp-rising standards, a shaft mounted therein provided with a duct, a condenser and an expansion coil oscillating with said shaft, a valveregulated pipe communicating between the expansion coil, an oscillating casing and cylinder fixed to said shaft and communicating with the condenser coil, pistons within said cylinder, and pipe connections between the. latter and the expansion coil.

' 2. A refrigerating machine comprising standards, a shaft mounted therein provided with a duct, a condenser and an expansion coil oscillating with said shaft, a valve-regulated pipe communicating between the condensing coil; communicates with p1pes'J which in turn communica ing a suitable valve H therein. Said conbranching with the ends of the oscillating cylinder L. A weighted lever Q is mounted upon a pivot N mounted in the casing and has slotted pivotal connections at ()"with the piston' stem R which has pistons S thereon movable within said cylinder. Said casing has denser and expanslon coil, an oscillating casing and cylinder fixed to said shaft and communicating with the condenser coil, pistons and stems connected thereto, and a weighted lever fixed to said stems and holding the pistons stationary as the casing osv cillates.

3. A refrigerating machine comprising standards, a shaft mounted therein provided with a duct, a condenser and an expansion coil oscillating with said shaft, a valveregulated pipe communicating between the condenser and expansion coil, an oscillating casing and cylinder fixed to said shaft and communicating with the condenser coil, pistons and stems connected thereto, a Weighted lever pivoted within the casing and hav-
